Optical-fiber holder having an optical-fiber winding framework capable of turning and inclining upward

Abstract

This optical-fiber holder comprises an annular optical-fiber winding framework. The optical-fiber winding framework includes an optical-fiber winding frame portion and a base portion provided as a turning axle of the optical-fiber winding framework. The optical-fiber winding frame portion has an optical-fiber containing groove formed along a periphery thereof. The base portion has an opening penetrating into an interior thereof and communicating with the optical-fiber containing groove at both ends. An optical fiber is wound and held in the interior of the base portion and the optical-fiber containing groove.

What is claimed is:  
     
       1. An optical-fiber holder comprising: 
       an annular optical-fiber winding framework including an optical-fiber winding frame portion having an optical-fiber containing groove formed along a periphery thereof, and a base portion provided as a turning axle of said optical-fiber winding framework, the base portion having an opening penetrating into an interior of said base portion and communicating with said optical-fiber containing groove at both ends,  
       wherein an optical fiber is wound and held in said interior of said base portion and said optical-fiber containing groove.  
     
     
       2. An optical-fiber holder comprising: 
       an annular optical-fiber winding framework including an optical-fiber winding frame portion having an optical-fiber containing groove formed along a periphery thereof, and a base portion provided as a turning axle of said optical-fiber winding framework, the base portion having an opening penetrating into an interior of said base portion and communicating with said optical-fiber containing groove at both ends; and  
       a cover inserted in a periphery of said optical-fiber containing groove so as to cover said optical-fiber containing groove.  
     
     
       3. An optical-fiber holder comprising: 
       an annular optical-fiber winding framework including an optical-fiber winding frame portion having an optical-fiber containing groove formed along a periphery thereof, and a base portion provided as a turning axle of said optical-fiber winding framework, the base portion having an opening penetrating into an interior of said base portion and communicating with said optical-fiber containing groove at both ends; and  
       a support including a support portion holding said base portion, and an opening leading said base portion into said support portion.  
     
     
       4. An optical-fiber holder comprising: 
       an annular optical-fiber winding framework including an optical-fiber winding frame portion having an optical-fiber containing groove formed along a periphery thereof, and a base portion provided as a turning axle of said optical-fiber winding framework, the base portion having an opening penetrating into an interior of said base portion and communicating with said optical-fiber containing groove at both ends, and having a positioning projection formed in a radial direction of said base portion on an outer surface thereof; and  
       a support including a support portion holding said base portion, an opening leading said base portion into said support portion, and a groove accommodating said positioning projection.  
     
     
       5. An optical-fiber holder comprising: 
       a plurality of annular optical-fiber winding frameworks each including an optical-fiber winding frame portion having an optical-fiber containing groove formed along a periphery thereof, and a base portion provided as a turning axle of said optical-fiber winding framework, the base portion having an opening penetrating into an interior of said base portion and communicating with said optical-fiber containing groove at both ends, and having a positioning projection formed in a radial direction of said base portion on an outer surface thereof; and  
       a support including a plurality of support portions each holding said base portion, an opening leading said base portion into each of said support portions, and a groove accommodating said positioning projection,  
       wherein said optical-fiber winding frameworks supported on said support are positioned in parallel close to each other by said positioning projection.  
     
     
       6. The optical-fiber holder as claimed in  claim 1 , wherein said base portion has a circular section and an axial form extending in an axial direction thereof, and includes a plane extending in said axial direction, first openings formed perpendicularly to said plane, a central portion and end portions divided by said first openings, and second openings so formed in said central portion and said end portions as to open in different directions in parallel with said plane. 
     
     
       7. The optical-fiber holder as claimed in  claim 3 , further comprising a lid unit provided on an end of said opening of said support, the lid unit being capable of opening and closing so as to cover said opening of said support and so as to cause said support portion to hold said base portion tightly by narrowing said opening. 
     
     
       8. The optical-fiber holder as claimed in  claim 3 , further comprising two locking units provided at an end of said support so as to position said support upright on a mounting substrate by being inserted into mounting holes formed on said mounting substrate.
